Patent abstract
A water-soluble polymer is used to change surfaces of the magnetic metal oxide nanoparticles to hydrophilic surfaces. The hydrophilic magnetic metal s oxide nanoparticles can be stably dispersed in a water matrix. Then, the hydrophilic magnetic metal oxide nanoparticles are mixed with hydrophilic resin, and a nanometer-scale uniform size of nanoparticles is maintained.
